Detective Doyle Carrick is awakened in the middle of the night by frantic banging on his front door, a sound followed by gunfire. Ron Hartwell, a complete stranger, is dying on his doorstep. A halfhearted investigation labels the murder a domestic dispute, with Miriam, Ron's widow, the sole suspect. When Doyle discovers the Hartwells both worked for a big biotech company, he suspects something else is going on, but it's not his case. Then, in a run-down North Philly hotel, Miriam tells him her story. In Haiti, Miriam and Ron had stumbled upon a corporate conspiracy that involved international politics and tainted food shipments. Doyle was their last hope to blow the whistle. Before she can tell him the rest, they are attacked by gunmen and she disappears again.

As Doyle follows her back to Haiti, and uncovers a web of deceit, intrigue and mass murder. Giant biotech corporations are working to topple the Haitian government. One is spreading a deadly allergy that will make the competitor's most popular product virtually poisonous and put millions of lives at risk.To prevent this, Doyle must enlist the help of his most dangerous enemies, and question everything he ever knew about himself and what it means to be a cop.
